I just did these too, plus the crank sensor. I don’t think I could have done it if my arms were much shorter and my hands and forearms any bigger. Not very fun, but satisfying knowing that I probably saved almost $500 over paying the dealership or a shop to do it.

My experience and tips:
The drivers side sensor took me about 5 minutes with a small 10 mm socket once I had gathered together all my stuff, removed the engine cover, and disconnected the battery.

The crank sensor took more prep work: remove the front passenger tire and wheel liner. The clip connector was a pain, and the access a bit tricky due to various lines in the way, but a small socket wrench with a deep 10 mm socket did the trick.

The passenger side camshaft sensor was the worst, as I anticipated from watching a few YouTube videos and reading several How-tos. And I couldn’t skip it because it was the one causing the problems (P0340). Access is a pain with wires and/or hoses in the way from nearly every angle (even moving my catch can out of the way), and there is only a limited amount of space between the block and firewall. I gave up after fighting the connector to the sensor, and the nearby connectors to other things were stuck too. I found that access from the bottom through the wheel well (as some have recommended) was practically impossible because it is a long reach to start with plus it involves going past several exposed screws and a sharp cornered exhaust shield. From the top left (looking towards the back of the engine) you have to navigate several hoses and wires, and it’s similar from the right plus you have to pretty much lay on top of the intake manifold to reach far enough.

Attempt #2 this evening took about 15 minutes. After reviewing the videos and other instructions again, to boost my optimism, I decided to try accessing more from the right (looking at the firewall) instead of the left and below and pulling out the screw holding it (small 10 mm socket) in before disconnecting. The key I found was laying on top of the engine and basically doing a wide bear hug across the intake manifold so I could get both hands back there, one from each side. The sensor didn’t want to back out easily, so I pried and popped out the first bit with a small screwdriver. More twisting and tugging got it out completely, and using one hand to push down the clip mechanism and the other to pull, I disconnected it.

Reverse order got it installed, replaced the engine cover, and reconnected the battery, started up fine, except for a bit of smoke out the exhaust, probably related to all the jostling I had to do with the catch can dumping some oil back into the manifold. Put the wheel well liner back in, tightened the lug nuts, and I’m hopefully good to go for another 130k miles and 10 years.

The cam position sensor and crank position sensor are the same part number. The crank position sensor is located on the right bank of the engine block (passenger side in the US), below the starter and rearward of the oil pressure switch. There's a picture on page EC-325 of the factory service manual.

The cam position sensor is located on the back side of the cylinder head, just below the valve cover and just above the engine coolant temp sensor. There's a picture of it on page EC-332.

Here's a link to the EC section of the 06 Frontier FSM:

The Nissan P/N is 23731-6N21A. Rockauto.com has the sensors in Hitachi brand, which makes the OE sensor, as well as NTK, which is also very good and makes the OE oxygen sensors for Nissan and is the same company as NGK, which makes the spark plugs for Nissan. The Hitachi is a little more money but has a longer warranty. Either is about 1/2 the price of genuine Nissan. It's best to stick with OE parts when it comes to these sensors.

Nissan 22448-EA000 is the part number for an ignition coil pack.
